摘要: A system for the nonvolatile storage of data, such as a postage meter system, employs microcomputer (104) coupled to two memories (106, 108). The first MNOS memory (106) requires data be applied more than predetermined time written into said while second EEPROM (108) is that less sufficient (108). Each 108) has address and lines, which are ports lines always at high value whenever addressed purpose writing or reading. In transactional accounting records stored in most current record can rapidly identified. program store causes microcomputer, when an error detected least one records, rewrite both full abbreviated
